Problems solved by technology

[0003] However, there is a random mismatch between the sampling capacitors, which will seriously affect the performance of the analog-to-digital converter. Although many methods are currently used to solve the random mismatch problem between the sampling capacitors, in order to obtain better performance of the analog digital converters, need better handling of random mismatch problems

Abstract

The present disclosure provides an analog-to-digital converter comprising: a sampling capacitor circuit comprising a sampling capacitor and configured to sample an input signal; and a conversion part used for performing analog-to-digital conversion on the output signal of the sampling capacitor.

Description

technical field [0001] The present disclosure relates to an analog-to-digital converter. Background technique [0002] In an incremental analog-to-digital converter, a sampling capacitor is required to sample an input signal, and the sampled signal is processed by an integrator and a quantizer to generate a digital signal. [0003] However, there is a random mismatch between the sampling capacitors, which will seriously affect the performance of the analog-to-digital converter. Although many methods are currently used to solve the random mismatch problem between the sampling capacitors, in order to obtain better performance of the analog Digital converters need better handling of the random mismatch problem. Contents of the invention [0004] In order to solve one of the above technical problems, the present disclosure provides an analog-to-digital converter. [0005] According to one aspect of the present disclosure, an analog-to-digital converter includes: [0006] a ...
